This is the APK file of the 2016 mobile game Pokémon Duel, which is no longer available to download. The game no longer works as the server it is required to use has shut down, but I decided to upload this anyways for preservation. These files are uploaded here strictly for preservation purposes and may be taken down upon request from The Pokémon Company or a lawyer representing The Pokémon Company, though it would be regrettable and such a request would be unfortunate to receive.
Install jp.pokemon.pokemoncomaster.apk as you would any other APK file. You will not be able to connect to the game server, as it has been shut down, but you can still install the app.
A unofficial replacement server called Kaeru Duel
, developed by Kaeru Team
, exists, and I have personally had success using this APK to connect to it. However, neither I nor Kaeru Team can endorse the use of an unauthorized copy of the game to access Kaeru Duel, and if you have issues, nobody will help you. This archive exists solely for preservation purposes.
